PHOENIX, Ariz. — The presence of lymphomas is a leading reason for condemnation of beef and dairy cows at slaughter.
They may have been infected with bovine leukosis virus.

Once considered a greater problem among dairy cattle, it has appeared in beef herds and could be a reason for poor productivity.
